I have been using this product for 5 months and it has made a significant difference to my energy levels and sleep pattern. Have also recommended it to my sister who is anaemic, she is much better after taking this B12.

Within two days of taking these tablets, my husband's "restless leg" problem simply disappeared. He has now taken them for 17 days and the dizziness that has plagued him for years (upon standing up) has almost completely gone - thank you!

This is the only form of B-!2 I will use because all others make me ill. I have been taking it for over three months now and see an amazing difference in my energy level. I have seven kids and am studying for my MPH degree. Believe me, this product works.

I wanted the best type of b12 for my new mostly vegetarian diet and its a great deal...my 50 year old mom also took it a few times and said she felt alot more energized... i will purchace this b12 again when i need more...

I could definitely tell a difference after taking it only a couple of days. I still have to adjust how often I take it; once a day is too much - I find it disrupts my sleep.
But great product, good for a vegetarian like me.

I have been on the B12 (cyancobalamin) injections for a while and when I stopped getting the same results, as when I initially started the injections I knew I was missing something. I did some research and found that the body sometimes does convert the cyancobalamin over to the methylcobalamin like it should. I thought it was worth a shot and I am amazed with the difference. It took a week or so, but wow! I feel great. It is easy to take, didn't taste bad (like some of my supplements), and just took a second (no water necessary). I was surprised that a lot of suppliers do not carry the methylcobalamin and mainly distribute the cyancobalamin. Thank you iHerb! It has made such a difference and is so simple to take that it will always be part of my daily routine. I can't imagine not taking it daily.

I had to look far and wide to find this great product which contains the dyes so common with B12 Sublingual. Im really happy with it. Within 7 days of use my Carpal Tunnel went from raging to mild. This pretty much saved my job. As always Natural Factors is a superior brand. Another fine PRODUCT OF CANADA to be proud of.
